IMPROVEMENT IN SOFAS.

Specication forming part of Letters Patent No. 170,678, dated December7, 1875; application filed September 27, i875.

To all 'whom it may concern Be it known that I, NE1L M. MACKENZIE, ofthe city and county of Providence, in the State of Rhode Island, haveinvented a new and useful Improvement in Sofas, for household use, whichimprovement is fully set forth in the following specification, referencebeing had to the accompanying drawings.

My invention consists in constructing a sofa in several parts, soarranged and combined that they are capable of being applied to varioususeful and convenient purposes, according to circumstances, in additionto thc ordinary uses of a sofa.

A central piece in the back of the sofa is arranged to slide up and turndown across the middle of the seat to a horizontal position Where it issupported at each end, forming a table. The central portion of the seatis slid l back to enable an occupant of' each end of the sofa to sitfacing the table, the two ends 0r seats remaining stationary, and beingheld together by strips reaching from one to the other, in such aposition as not to interfere with the occupants of the seats. Anotherchange is to convert the two ends of the sofa into two easy-chairs, byremoving entirely the central portions of the seat and back abovereferred to, and disengaging the other connecting parts.

In the accompanying drawings, Figure l is a view of my invention, withthe parts arranged for use as an ordinary sofa. Fig.2 represents thecentral sliding portion of the back, arranged as a table across andabove the central portion of the seat, the middle portion of the seatbeing drawn back. Fig. 3 represents one end of the sofa detached for useas an easy-chair. Fig..4 is a section of the sliding back, showing adowel-pin near the bottom, which runs in a groove, and helps to keep thetable in position.

Bis the movable or sliding section ofthe back of the sofa, which ismoved up and down in grooves g. At the back of the groove gis a narrowergroove, g', to receive the dowelpin d. This latter groove extends alittle above the sides of groove g, to allow the back to fall forward,after being drawn up, and rest with its lower end on the top of thesesides, with the dowels or journals in their grooves. This table-rest isshown at i", Fig. 3. The other end of the table is supported by one ormore legs or braces. A single rod, :0, with one end placed in the centerof the rosette c, and the other in a recess or step, s, as' shown inFig. 5, will be sufficient. This rod, when not in use, may be slippedinto a loop on the under side of the sofa, so that it may be always athand.

Instead of such a support as described, ornamental pieces may be hingedto the front part of the back near the top, to be used as braces orsupports, when the back is converted into a table. The height of thetable above the seat can, of course, be controlled by the construction.

S is the central section of the seat, constructed to slide eitherbackward or forward, by means of tongues and grooves, shown at t, Fig.1, the grooves also appearing in Figs. 2 and 3.

The connecting strip or strips which fasten the ends of the sofatogether extend across the bottom and back, and are held by thumbscrews,so as to be readily detached. Such a connecting rod or strip is shown aty, in section, Fig. 5, and in dotted lines, Fig. 6, which is a plan ofthe sofa, with the central movable portion of the back in horizontalsection.

When these strips are removed, and the central portions B and S takenout, there remain two easy chairs, which are portable, and can be placedinany part of a room to be used as such, each having four legs, or theycan be brought together, so as to form a less extended sofa.

What I claim as new, and desire to secure by Letters Patent, is-

l. A sofa, the bach of which is constructed with a central section, B,that can be drawn or slid up, and laid transversely across and above theseat in a horizontal position, substantially as and for the purposes setforth.

2. A sofa, having a seat providedwith a central section, S, movableforward or backward, as described, and a back provided with a centralmovable section, B, substantially as set forth.

3. A sofa, composed of four principal parts,

viz: the movable central back-section, the movable central seat-section,and the Vtwo end chairs or sofa sections, arranged together asdescribed, and capable of separation, substantially in the manner andfor the purposes specified. I Witnesses: NEIL lVI. MACKENZIE.
